GAS-HEATER.

Application filed November 26, 1913.

To QM whom it may concern Be it known that I, Fnnnnnrox E. Donna, a citizen of the United States, residing at the city of Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Gas-Heaters, of which the following is a specification. a

The object of my invention is to produce a cheap, simple and efficient gas heater or stove.

My new gas heater is formed of three compartments, the front compartment where the fumes and products of combustion enter and pass upward, a rear compartment from which the fumes and noxious gases pass up through and out of a fume pipe which is connected. to said rear compartment; and between the front and rear compartment I provide a center compartment into which the cold air is carried upward and out through the top grating, the center compartment also being inclosed by s1de walls. The front and rear compartments are connected by a series or multiplicity of tubes, the tubes passing through the center compartment.

The object of my invention 18 to produce a gas heater which will consume a min mum amount of gas and produce a maximum amount of heat.

The various features of my invention and its advantages will readily become apparentfrom a perusal of the following specification.

In the accompanying drawing forming part of this specification: Figure (1) is an isometric view of my new gas heater, Fig. (2) is a section taken on line 22 of 1, and Fig. is a section taken on line 33of Fig. 1.

The front compartment is formed between spaced walls 1 and 2 and the rear compartment is formed between spaced walls 3 and l, closed at top by hoods 5 and 6 respectively. The wall (1) is open at its lower end at (7) and the wall at its lower end is flared and extends backward to make room for the gas burner (8), the walls 3 and 41 both extending to the bottom, the wall 1) inclined somewhat at bottom toward wall (3), both compartments being closed at bottom, except where wall (1) is interrupted by space (7). The sides are formed of walls (9) which extend from the top to bottom of the stove. The rear compartment Specification of Letters Patent.

has a flue hole cut in the hood (6) to receive the flue pipe (10). The central compartment between Walls 2 and 1 is covered by a grating (12), and the heater is supported on legs (13). In the central compartment, extending between the walls 2 and 4. of the front and rear compartments, I place a series of tubes (11). These tubes are not in straight alinement but are placed irregularly. The gas comes in through gas pipe (15), and (16) represents the mixer (see Fig. 1).

The mixed gas and air are consumed by burner (8) and pass up as heat and products of combustion in the front compartment between walls 1 and 2 as shown by arrows and pass through the series of tubes (14:), as shown by arrows and then enter the rear compartment between walls 3 and 41, as shown by arrow and then rise as fumes and pass out of the flue or fume pipe (10). The cold or fresh air passes up through the open bottom of central compartment between the walls 2 and 3 and strikes the pipes or tubes (14:) and passes out through the grating (12) into the room.

A great deal of heat will be emitted from this gas stove as the front andrear compartments are heated by the hot products of combustion as well as the pipes (14:) and the air passing up and striking the pipes (14) is heated to an increasing intensity as it passes up between the tubes into the room inasmuch as it is thrown into contact with these various hot tubes, and the gas consumed will be proportionately small considering the amount of heat produced, making the stove both cheap and highly efficient.

It will be noticed that I provide a front or heating chamber or compartment and a rear fume chamber or compartment and these two chambers are spaced to form the central compartment which is inclosed with side walls so that these chambers not only produce heat in themselves but they also form an inward and outward radiating surface for the heat, thus enabling me to produce a large radiating surface in a small stove.

The stove may be made of any size and out of any suitable material and of any contour. The tubes (14) are shown annular but they may be formed of any shape or size and vary as to their number; the more employed, the greater the heat produced.

While I have described and illustrated one specific construction of my new gas heater, it Will be readily seen that it is capable of considerable modification without'departing from the principle and spirit of the invention, and I Wish to be understood as not limiting myself to such specific construction, but that such modificationswill' partment formed of spaced walls and reaching up from said burner-and closed at the top, a rear fume compartment formed of spaced walls, said front andrear compartments foii'ming continuous chambers, and

spaced to form a central compartment bebottom for the reception of cold air, walls tween them, a multiplicity of small tubes in said central compartment, each communicating with the front and rear compartments, said central compartment being open at the at each side of the central compartment, said compartments all being inwardly heated and their outer walls also forming a radiating surface for the heat.

2. In a gas heater of 'the character described, aburner, a combustion chamber and a fume chamber, each formed of spaced walls, said combustion and fumechambers spaced to form a cold air chamber between Stateof ()hio this 2 1-. day of November 1913 1 4,
